MEANS FOR TRANSMITTING AND EQUALlZING' VARIABLE POWER.

SPECIFICATION forming part of Letters Patent No. 746,323, dated December8, 1 Application filed January 20, 1903. Serial No. 139,790. (No model.)

To aZZ whom it may concern:

Be it known that I, Lo'r E. GA YLORD, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented certain new and useful Improvementsin Means for'lransmitting and Equalizing Variable Power, of which the following is aspecification.

My invention relates to improvements in means for transmitting andequalizing variable power, and particularly for equalizing the variablepower derived from a windmill.

To this end myinvention consists in the features of construction andcombination hereinafter particularly described and claimed.

In the accompanying drawings, forming part of this specification,Figure1 is a front elevation of a drum and connected parts forming part of myinvention. Fig. 2 is a top view of the same with the drum in section.

Fig. 3 is an end view thereof. Fig. 4 is a section on line w m of Fig.2, and Fig. 5 is a section of connected mechanism for regulatdrumintermediate of said gears is constructed with a spider 9, forming asupport for a transverse shaft 10, upon the opposite ends of which are.loosely journaled the beveled pinions 11 and 12, intermeshing with thegears 7 and 8, as shown in Fig. 2. Upon the outer end of the shaft 3 issecured a pulley 13, adapted to be connected with a source of variablepower, as a windmill. In order to prev'ent any backward rotation of theshaft 3, I secure thereon a pulley 14, with the periphery of whichengages a suitable pivoted shoe 15. Upon the outer end of the shaft 2 issecured a pulley 16, which serves as a transmission-pulley.

In order to regulate the source of power when a certainspeed is reached,I provide the mechanism shown in Fig. 5. This consists of a drum 23,having suitable journalsupport (not shown) and carrying a cable 17,

the outer end of which is connected, as shown in Fig. 5, with the weight6. The drum 16 carries a pinion 18, which intermeshes with agear 19,connected by rods 20 and 21 with the cut-off mechanism (not shown) ofthe wind.-

mill or other suitable source of power. 'In

order to actuate the drum 16 to wind up the cable when the weight 6 islifted,-I provide the drum with the weight 22 depending from the side ofthe drum opposite to the main weight 6.

In operation the windmill or other source of variable power will drivethe pulley 13, together with its shaft 2 and gear 8. As said gear 8 isrevolved, the intermeshing pinions 11 and 12 will be rotated upon theirsupporting-shaft 10, actuating the gear 7 and transmitting power throughthe shaft 2 and transmission-pulley 16. The weight 6, carried by thedrum, issuch that when the windmill isrunning at normal speed all of thepower will be transmitted from the shaft 3 through the gearing to, theshaft 2, allowing the drum to remain stationary; but when running atgreater than normal speed the beveled pinions 11 and 12 will turn atagreater relative speed than the gear 7, causing the drum 4 to berotated to wind up the cable 5. When, on the other hand, the windmilltravels at less than normal speed, the weight will beginto unwind thecable and accelerate the rotation of the gear 7 and transmission-shaft2. As the weight 6 is lifted by the winding of the cable 5 the drum 23will actuate the gear 19 and connecting-rods 20 and 21, so that as theweight 6 is lifted the cut-ofi mechanism of the windmill (not shown)will be actuated to decrease the power. As the weight 6 lowers, thereverse operation of the drum 23 and connected parts takes place toincrease the power. In other words, the load represented by the drivenparts counterbalances the wind-. ing-drum when the gear is driven at acertain speed, so that the winding-drum remains stationary. Consequentlywhenthe speed of the gearing increases part of its. power will betransmitted to the drum, winding up the cable to maintain theequilibrium of the drum and load, and when the speed of the gearingdecreases the cable will be unwound by its weight to maintain suchequilibrium.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. Means for transmitting variable power, consisting of a shaftconnected with the parts to be driven, a drum loosely mounted upon saidshaft, a weighted cable carried by said drum, gearing interposed betweenthe drum and source of power, said gearing being so constructed,arranged and weighted that said drum will remain stationary when thegearing is driven at a certain speed, but will be actuated by saidgearing to wind up the cable when the speed of said gearing increases.

2. Means for transmitting and equalizing variable power, consisting of ashaft having means of connection with the parts to be driven, a drumloosely mounted upon said shaft, a weighted cable carried by said drum,a pair of gears operatively connected with the source of power and withsaid shaft, said gears being so constructed, arranged and weighted thatwhen driven at a certain speed they will actuate said shaft and allowsaid drum to remain stationary, and will actuate said drum to wind upsaid cable when driven at a greater speed.

3. Means for transmitting and equalizing variable power, consisting of ashaft connected with the parts to be driven, a drum loosely mounted uponsaid shaft, a weighted cable carried by said drum, gearing connectingsaid drum and shaft with the source of power, said gearing being soconstructed, arranged and weighted as to actuate said shaft when drivenat a certain speed, and to actuate both the shaft and drum when drivenat a greater speed, and means actuated in the winding of said cable forshutting off the source of power.

4. Means for transmitting and equalizing variable power, consisting of ashaft connected with the parts to be driven, a gear carried by saidshaft, adrum loosely mounted upon said shaft, a weighted cable carriedby said drum, a pair of rotatable gears carried by said drum andnormally intermeshing with the gear mounted upon said shaft, and meansfor driving said gears from the source of power, substantially asdescribed.

5. Means for transmitting and equalizing variable power, consisting of ashaft connected with the parts to be driven, a gear carried by saidshaft, a drum loosely mounted upon said shaft, a weighted cable carriedby said drum, a pair of beveled pinions supported upon a transverseshaft carried by said drum, said pinions inter-meshing with said gear,and a second gear inter-meshing with said pinions and connected with thesource of power.

6. Means for transmitting and equalizing variable power, consisting of ashaft connected with the parts to be driven, a beveled gear carried bysaid shaft, a drum loosely mounted upon said shaft, a weighted cablecarried by said drum, a pair of beveled pinions loosely mounted upon atransverse shaft carried by said drum and intermeshing with the gearcarried by the drum-supporting shaft, a second shaft connected with thesource of power, and a gear carried by said shaft and intermeshing withsaid pinions.

In testimony whereof I affix my signature in presence of two witnesses.
